High Flow 400 CPSI Catalytic Converter For EU5 Auto Exhaust 118x152mm

Restore Emissions Compliance While Boosting Exhaust Flow

The KSRCAT High Flow 400 CPSI Catalytic Converter delivers targeted Euro 5 emission control paired with unrestricted exhaust passage for noticeably improved engine response and power output. Engineered with a dense ceramic honeycomb substrate, this unit filters harmful gases through efficient catalytic conversion—transforming carbon monoxide, unburned hydrocarbons, and nitrogen oxides into safe carbon dioxide, water vapor, and nitrogen. Unlike overly restrictive factory converters that choke horsepower and increase fuel consumption, the 400 CPSI density maintains optimal backpressure while meeting strict automotive environmental standards.

Performance Tips & Practical Uses

• Direct OEM Replacement: With a precise diameter of 118mm and a length of 152mm, this converter slots directly into standard stock exhaust layouts without requiring custom fabrication or pipe cutting.
• Manufacturing Tolerance: A standard variance of ±1mm is built into the production process and falls well within normal operating limits for smooth exhaust routing and gas filtration.
• Professional Welding: Secure proper joint alignment before welding. The accompanying store videos demonstrate correct heat application and positioning to prevent cracks or exhaust leaks during operation.

Important Installation Notes

This component is engineered strictly for replacing original manufacturer catalyst dimensions. It is not compatible with modified, aftermarket, or custom-tuned exhaust architectures. Failure to follow proper welding techniques or resulting disengagement due to loose joints voids installation guarantees. Always verify vehicle exhaust measurements before purchase.
